2.6 CAN bus (NMEA2000 Connector)
Every NavNet TZtouch2 has one CAN bus connector (micro style connector). All
NavNet TZtouch2 must be connected to the same CAN bus backbone. To connect the
NavNet TZtouch2 and DRS (radar sensor), use “Ethernet Bridging” to link the DRS
CAN bus and the NavNet TZtouch2 CAN bus data (see section 2.6.2).
To power the NavNet TZtouch2 from the CAN bus port, the MULTI cable must be
supplied with a 15 VDC power input.
What is CAN bus?
CAN bus is a communication protocol (NMEA2000 compliant) that shares multiple
data and signals through a single backbone cable. You can simply connect any CAN
bus devices onto the backbone cable to expand your network on-board. With CAN
bus, IDs are assigned to all the devices in the network, and the status of each sensor
in the network can be detected. All the CAN bus devices can be incorporated into the
NMEA2000 network. For detailed information about CAN bus wiring, see “FURUNO
CAN bus Network Design Guide” (Type: TIE-00170) on Tech-Net.
2.6.1 How to connect the TZTL12F/TZTL14F to CAN bus equipment
Below is an example of two TZTL2 units, connected via CAN bus to CAN bus sensors.
2.6.2 How to connect the TZTL12F/TZTL15F to DRS radar sensors
Note: The DRS4DL sensor does not have CAN bus connectors attached.
In addition to the CAN bus port found on the NavNet TZtouch2, all DRS radar sensors
have one powered CAN bus port (terminal strip connector). The total number of
sensors that can be connected to the DRS CAN bus port without external power
connection depends on power consumption. The DRS can supply up to 1 amp
(20LEN) to the DRS CAN bus network.
Note: Do not directly connect the radar sensor and TZTL unit via the CAN bus ports.
Below is an example of the TZTL2, connected to each type of DRS radar sensor.
